摘要： PURPOSE:To easily correct higher convergence error and raster distortion by arranging a sheet coil having the same shape as an external shape of a funnel on the necessary external face and supplying a current synchronized with deflection current. CONSTITUTION:In an aperture between a funnel 2 and a deflection device 9 or on the external face of the large diameter of the funnel 2, a sheet coil 33 is arranged in the same curved face shape as the boundary part external face between the large diameter part of the funnel 2 and a neck 5, or the large diameter external face of the funnel 2. When current synchronized with the current flowing in a horizontal deflection coil 10 or a vertical deflection coil 11 of the device 9 is supplied to the coil 33, magnetic field distribution formed by the coil 33 according to appropriate setting of conductive flux shape of the coil 33 and magnetic field distribution ganerated by the deflection device 9 are supervised on each other so that complicated magnetic field distribution for substantially correcting higher convergence error and raster distortion can be easily, simply formed.

摘要： PURPOSE:To restrain the vibration of a mask frame from being transferred to a mask main body to prevent colors from being incorrectly positioned by forming an external raised part in the skirt part of the mask main body in opposition to the external raised part of a mask frame. CONSTITUTION:The tip of the skirt part of a shadow mask main body 31 located in opposition to a fluorescent screen 3 inside a panel 1 is bent outwardly to form an external raised part 35. The raised part 35 is provided in opposition to an external raised part 39. This constitution increases the flexural strength and spring coefficient of the skirt part of a mask main body 31 and the sidewall part of a mask frame 32 and restrains the torsional vibration of the mask frame 31 as well as the transfer of the amplitude of the mask frame 31 to the mask main body to provide a color picture tube which rarely causes colors to be incorrectly positioned.

摘要： PROBLEM TO BE SOLVED: To provide a color picture tube having sufficient curved surface holding strength even if a shadow mask is flattened, and a manufacturing method therefor. SOLUTION: In this color picture tube, a substantially rectangular shadow mask is arranged on the inside of a panel having a substantially rectangular effective part, and this shadow mask comprises a substantially rectangular frame and a substantially rectangular mask body where a large number of electron beam passing holes are formed in an effective surface composed of a curved surface opposed to the effective part and a peripheral part of this effective surface is fixed to the frame. In this case, the effective surface 23 of the mask body 21 is formed in a cylindrical curved surface on which a radius of curvature in the major axis direction is set almost infinite and a radius of curvature in the minor axis direction is set almost constant.

摘要： PURPOSE: To improve color purity of the color picture tube provided with a shadow mask of which a substantially rectangular shaped effective surface is made of a curved surface and constituting an electron beam passing pore column in which the electron beam passing pores on the effective surface extend in column along the short axis of the effective surface by specifying the tilt of the electron beam passing pores. CONSTITUTION: An electron beam passing pore column 42 is bent to different shapes depending upon the position on an effective surface 34, and an electron beam passing pore 41 is tilted along the electron beam passing column pore 42. In an area where the till on the long side of an effective surface 34 of this electron beam passing pore 41 is pinched by means of the short side of the effective surface 34 and a point 1/4 inside of the dimensions between short sides from this short side, the electron beam passing pore 41 end part of the lon side is tilted the maximum in the positive direction closer to the short-axis direction of the effective surface 34 than the opposite side end part, and in the 1/3 inside of the dimensions between short sides from the long side, the tilt increases as the distance from the short axis of the effective surface 34s increases, and the tilt decreases or is inverted as it approaches to the short side so as to have the minimum value.
